<Support bar 1a>
Fig. 5 (a) is the top view for showing support bar 1a, and Fig. 5 (b) is C-C sectional views, and Fig. 5 (c) is D-D sectional views.Support bar 1a Supported by hollow steel pipe.Support bar 1a meets regulation generally using ferrous materials such as spring steel, STK11a, STK13A, STK13C The metal materials such as the steel of intensity and fatigue strength (endurance limit) can all be used, in the absence of specifically limited.For example, support bar 1a In addition to using ferrous materials, aluminium, titanium and other metal materials can also be used.
Support bar 1a is formed by the hollow pipe two ends of specific length after being plastically deformed and sealing into tabular.That is, support Bar 1a has the sealing 1a3 of the hollow pipe 1a1 of central portion, the flat board 1a2 at both ends and edges at two ends portion.Hollow pipe 1a1 is formed Material tubulose.
Flat board 1a2 is formed by the stamped tabular that is processed into end of hollow pipe 1a1.By this procedure of processing, support The flat board 1a2 of bar 1a spreads relative to the hollow pipe 1a1 of center side in spade.
By forming flat board 1a2, axle rotation is likely to occur between the housing 1b that the both ends of support bar 1a are respectively configured There is the situation of phase difference in angle.In this case, carrying out punching press in the leading section of a side end of the tubing to forming support bar 1a After processing, flat board 1a2 clear and definite its position of a side end can be first detected when carrying out punch process to another side end.In addition, making this The angle of tubing rotational phase difference, you can realize punch process in the leading section to another side end of tubing.Wherein, the stabilization of Fig. 4 Show that phase difference is the situation of 180 degree in connecting rod 1.Sealing 1a3 is the end of the flat board 1a2 at two ends through plastic extruding deformation, place Formed after state, i.e. air-tight state is sealed.
That is support bar 1a forms sealing 1a3 by the front edge of the tubing of specific length through extruding.In addition, from sealing 1a3 To the flat board 1a2 of writing board shape, by being changed into the tapered portion 1a4 of tubulose, the hollow pipe 1a1 of the tubulose of center side is eventually arrived at.
The size S1 designs counted from the end edge of the sealing 1a3 of support bar 1a are for about 0.5-3mm.Seal the thickness of 1a3 Degree is designed as the size of 10%-35% thinner than the twice of tubing thickness.That is, sealing 1a3 is obtained than tubing through plastic deformation The size of thickness of thin about 10%-35%, then through sealing (closed) formation.By this procedure of processing, it can be ensured that support bar 1a's Sealing (closed) property.For example, the tubing of diameter 10mm thickness 1.2mm is used for the situation of support bar 1a, then by than its twice The dimensional thickness S2 of the scope of the thin 10%-35% of thickness 2.4mm is set to 1.9mm.

The flat board 1a2 for being formed at end is substantially all and is designed to tabular, because of the material of support bar 1a and through being integrally formed Housing 1b resin material difference produced by coefficient of expansion difference may cause shaping when there is space, gap etc..For example, Inprocess shrinkage step when insertion in inserts mold process is molded, the resin for being usually formed housing 1b can coat support bar 1a, But there is support bar 1a and are applied in that greatly situation of power of support bar 1a etc. cannot be coated to resin in actual capabilities.
Therefore, this support bar 1a uses following structures.As shown in Fig. 5 (a)-(c), writing board shape flat board 1a2 or Its recess 1a5 that concave shape is nearby set.Recess 1a5 can carry out punching press and add while flat board 1a2 and sealing 1a3 is formed Work, it is also possible to carry out punch process again after flat board 1a2 is formed.
Have benefited from the presence of recess 1a5, it is fixed that support bar 1a obtains strength with the resin for forming housing 1b.Therefore formed empty Heart pipe 1a1, flat board 1a2, the tubing of sealing 1a3 can carry out cation electrodeposition electrophoresis painting dressing or electroplating processes in the form of monomer. By the step, the support bar 1a shown in Fig. 5 is produced.
<Housing 1b>
Housing 1b is formed from a resin as described above, it is preferred to use the resin of addition reinforcing material.Mother metal on housing 1b, can To use PA66 (Polyamide 66), PA6 (Polyamide6), PPS (Polyphenylenesulfide), POM (Polyacetal) engineering plastics or the superengineering plastics such as.Engineering plastics are that a kind of intensity is outstanding, strengthen heat resistance etc. The industrial plasticses of specific function.Superengineering plastics are that performance is particularly pertinent in engineering plastics, when can be long in high temperature environments Between the resin that uses.For example, conventional engineering plastics include FRP (fiber-reinforced plastic), GRP (fiberglass-reinforced plastic), CFRP (carbon fiber reinforced plastic).
For example, reinforcing material mainly uses thin glass fiber.To ensure to strengthen under effect and high temperature (about 80 DEG C) Intensity under strength ratio normal temperature (about 23 DEG C) is high by more than 50%, and content is preferably about more than 25%.Further, it is contemplated that mouldability and note In the life-span of molding machine, the upper limit is preferably arranged to 60% or so.That is, the containing ratio of reinforcing material preferably about more than 25% about Less than 60%.In addition, reinforcing material can also be using the material beyond glass fibre.
As shown in figure 4, the case for this embodiment, the housing 1b of the another side side of support bar 1a according to one side side shell The shape of body 1b inversely makes shaping, and the housing 1b of one side side is identical with the housing 1b shapes of another side side.
Housing 1b formed the sealing 1a3 of covering support bar 1a, flat board 1a2, one of tapered portion 1a4 and hollow pipe 1a1 The shape divided.Housing 1b has receiving portion 1b1 (reference picture 4 (a)) and fixed part 1b2.The thickness of housing 1b be set as 4mm with Under.The thickness of housing 1b is set as that below 4mm can prevent the spaces such as bubble.
Formd on receiving portion 1b1 and justified for accommodating the bottom that has of the entity portion 12a of ball seat 12 and the bulb 10b of ball stud 10 The receiving hole 1b3 of tubular.Sealing 1a3, flat board 1a2, tapered portion 1a4, the Yi Jikong of fixed part 1b2 from the fixed support bar 1a in inside A part of heart pipe 1a1.The outside of the perisporium of the receiving hole 1b3 of receiving portion 1b1 form 3 flange 1f1 of circular plate shape, 1f2、1f3。
As shown in Fig. 4 (b), in order to improve the intensity between flange 1f1,1f2,1f3, configure in flange 1f1,1f2,1f3 Direction of principal axis supercentral reinforcement reinforcement r1, r2, r3 and reinforcement reinforcement r form the shape for linking flange 1f1,1f2,1f3 Shape.Flange 1f1,1f2,1f3, reinforcement reinforcement r, r1, r2, r3 can be formed can bear the bulb 10b's from ball stud 10 The structure of external force.
The base plate 1bt of receiving portion 1b1 forms multiple entity portion 12a for ball seat 12 and carries out hot riveting 12k (references Hole 1k1 Fig. 3).The resin (about 3-4mm is thick) and cladding support bar 1a of the barrel surface of the receiving hole 1b3 of receiving portion 1b1 will be coated Sealing 1a3 front edge resin between size S3 (reference picture 4 (a)) control in the space of 2-3mm or so.Therefore can With the resin thickness for ensuring the front edge of the sealing 1a3 for coating support bar 1a and the receiving hole 1b3 for coating receiving portion 1b1 The resin thickness of barrel surface will not be worn.
The front edge of the sealing 1a3 of support bar 1a is wrapped by the resin of the thickness S4 (reference picture 4 (a)) of 3-4mm or so Cover.Additionally, in order to ensure forming the resin of flange 1f1,1f2,1f3, reinforcement reinforcement r3 from receiving portion 1b1 to fixed part 1b2 Resin transition smooth-going, it is to avoid stress concentration, at the same improve intensity, entreat side shifting thereto from the front edge of support bar 1a The position that size S5 (about more than 2mm) (reference picture 4 (a)) intersects, its thickness and the resin of the center side of cladding support bar 1a Thickness is substantially consistent.Therefore can realize (strengthening comprising flange 1f1,1f2,1f3, reinforcement from the resin for forming receiving portion 1b1 Muscle r3) to the smoothly transition of the resin for forming fixed part 1b2.
<The shaping of stabilization connecting rod 1>
Using the support bar 1a (reference picture 5 (a)-(c)) by the surface treatment, being molded by inserts makes housing 1b integrations The both ends of support bar 1a are fixed to, stabilization connecting rod 1 is produced.Injection forming mold is the situation of horizontal open and close type, to detection The front end of support bar 1a, it is ensured that flat board 1a2 (reference picture 5) extends extended surface and keeps level in the horizontal direction, solid using tool Determine support bar 1a.
When closing injection forming mold, the cross section for clamping support bar 1a is the hollow pipe 1a1 of circular.Then, to The injection forming mold resin by injection of closing, opens injection forming mold after cooling, now the two ends of support bar 1a are overall respectively Fixed shell 1b.The shaping of housing 1b can be carried out in the one side of support bar 1a respectively, it would however also be possible to employ slidingtype, two ends are simultaneously Carry out forming operation.By above step, the forming operation of stabilization connecting rod 1 (reference picture 4) is realized.
Following effects can be realized using the structure.
1. by stablizing the receiving portion 1b1 of connecting rod 1 using with the addition of the resin and metal pipe material of reinforcing material, so as to realize steady Determine the lightweight of connecting rod 1.Compared with all steel stabilization connecting rod made of iron, weight can reduce about 30%.Additionally, stabilization connecting rod 1 can To reach the weight equal with full resin-made stabilization connecting rod, lightweight is realized.
2. it is the metal tubulation materials such as steel pipe due to stablizing the bar portion of connecting rod 1, the longitudinal elastic coefficient of such as steel is about 210GPa, it disclosure satisfy that the displacement (elastic lifting amount) of relative given load as conventional steel support bar.
3. because the size S1 counted from the edge at the both ends of the support bar 1a for stablizing connecting rod 1 is through the modeling of about 0.5-3mm Property deformation and sealing form sealing 1a3, therefore sealing (seal) be protected.Also just because of this, to the table of support bar 1a When face carries out cation electrodeposition electrophoresis painting dressing or electroplating processes, can prevent water, solution from invading inside support bar.Additionally, carry out When the inserts of stabilization connecting rod 1 is molded, resin can be prevented to be flowed into the inside of support bar 1a.Meanwhile, in actually used vehicle, Can also prevent the liquid such as moisture from invading the inside of stabilization connecting rod 1, effectively prevent because corrosion etc. is caused aging.
4. it is plastically deformed the both ends of the support bar 1a for stablizing connecting rod 1, is formed from hollow pipe 1a1 in the flat of spade extension Plate 1a2, the resin of the sized fraction more than center side of end side resin.Even if therefore applying to pull out support bar to stablizing connecting rod 1 The load in the direction of the housing 1b on 1a direction of principal axis, as long as resin is not destroyed, housing 1b would not depart from from support bar 1a.
5. due to foring flat board 1a2, therefore appearance between the housing 1b at the both ends of support bar 1a ought be separately positioned on There is the situation of phase difference in the angle of axle rotation, the flat board 1a2 of side can be first positioned as benchmark, then again to opposite side Flat board 1a2 carries out forming operation, and processing is more prone to.
6. the support bar 1a of stabilization connecting rod 1 is fixed by the inprocess shrinkage of the resin of housing 1b, but due to the tree of housing 1b Fat is different from the linear expansion coefficient of the metal material of support bar 1a, it is thus possible to space, gap etc. occurs.But, as long as Recess 1a5 with concave shape is set near the flat board 1a2 of the end of support bar 1a, it is possible to by grappling physically Effect suppresses space, the generation in gap.
7. it is about 3-4mm due to forming the resin thickness of housing 1b, is provided with convex around receiving hole 1b3 (reference picture 4 (c)) Edge 1f1,1f2,1f3, therefore, it is possible to ensure the intensity of the perisporium to form receiving hole 1b3, it is to avoid its external force is damaged.
8. as shown in figure 4, the central part of the direction of principal axis of flange 1f1,1f2,1f3 of circular plate shape forms the benefit of perpendicular wall Strong reinforcement r1, r2, r3.Additionally, forming the resin and reinforcement reinforcement r3 of flange 1f1,1f2,1f3 in the front end of support bar 1a The length of side shifting size S5 (=about more than 2mm) (reference picture 4 (a)) is entreated to be intersected and be molded thereto in edge.Therefore shell The power (extraction load and press-in load of ball stud 10 etc.) of the central axis direction of the receiving hole 1b3 of body 1b can improve to form appearance Receive the rigidity of hole 1b3 resin seam.Additionally, the resin of receiving hole 1b3 can also become to the transition of the intensity of support bar 1a sides Smooth-going.
9. due in the resin for forming housing 1b, containing the reinforcing materials such as thin glass fiber, therefore housing 1b is being improved Intensity while can also realize lightweight, and do not interfere with the life-span of injection moulding machine.
By above step, can realize that displacement is small, lightweight and intensity stable connecting rod 1 high.
